The Alexandria Police Department is investigating an armed robbery and carjacking that allegedly occurred about 10 p.m. Tuesday night at Walden Points Apartments on Twin Bridges Road, according to Alexandria Police.

Upon arrival to the scene, officers talked to a woman who reported an unknown man approached her 2000 Nissan Xterra, pointed a handgun at her and demanded she let him in her vehicle. She accused the man of having the handgun pointed at the back of her head while she drove off.

The woman told police the man instructed her to drive towards Masonic Avenue and Horseshoe Drive. She said she didn’t know the address of the Masonic Avenue location he forced her to exit the vehicle.

Investigators said before the gunman demanded the woman get out of the car, he allegedly asked her if she had any money and wanted her driver’s license. Officers said the man took $400 from the woman and told her that if she notified police, he would come to her residence and get her.
